Area of a Triangle
jek_recluse [69]

Answer:

3.51 (round to the nearest hundreds)

Step-by-step explanation:

PART A

slope of the line passing through AC : (6-1)/(1-2) = 5/-1 = -5

equation of the line passing through B and perpendicular to AC:

y-3 = 1/5(x-3)

y-3 = 1/5x -3/5

y = 1/5 x - 3/5 + 3

y = 1/5 x + (-3+15)/5

y = 1/5 x + 12/5

PART B

line that passes through the points A and C

y-1 = -5(x-2)

y = -5x+10 + 1

y = -5x + 11

Interception of the lines

y = 1/5x + 12/5

y = -5x + 11

-5x + 11 = 1/5x + 12/5

-25x +55 = x + 12

26x = 43

x = 43/26

y = -5(43/26) + 11

y= -215/26 + 11

y = (-215+286)/26 = 71/26

D (1.65, 2.73)

PART C

AC = \sqrt{(1-2)^2 + (6-1)^2} = \sqrt{1 + 25} = \sqrt{26} = 5,09902

BD = \sqrt{(3-1.65)^2 + (3-2.73)^2} = 1,376735

PART D

AREA = (5,09902 * 1.376735)/2 = 3,509999

Perform the indicated operation.<br> h(n)=n-3<br> g(n)=-2n² + 2<br> Find (hºg)(n)
Anni [7]

Step-by-step explanation:

h(n) = n - 3 \\ g(n) =  - 2 {n}^{2}  + 2 \\  \\ (h.g)(n) = h(n).g(n)  \\  = (n - 3).( - 2 {n}^{2}  + 2) \\  = n( - 2 {n}^{2}  + 2) - 3( - 2 {n}^{2}  + 2) \\  =  - 2 {n}^{3}  + 2n + 6{n}^{2}   - 6 \\    \red{\boxed {\bold{\therefore \: (h.g)(n) = - 2 {n}^{3}+ 6{n}^{2} + 2n  - 6}}}

segment if a is a perpendicular bisector of segment BD if the measure of angle frd is represented by the expression 7x + 6 find
GalinKa [24]

Answer:

x = 12

Step-by-step explanation:

If it is a perpendicular bisector, then the intercepting angles are always 90°.

If that is the case then we simply set the expression 7x + 6 equal to 90 and solve for x. We should get 12 as our answer.
